Pressure Relief Valve Assembly

Abstract

A pressure relief valve assembly includes a frame defining a ventilation port, a valve flap attached to the frame to open and close the port, a cover with a cover opening, a valve core rotatably arranged relative to the cover and having a valve plate, and a driving device coupled to the valve core. The driving device rotates the valve core between a fully closed position, in which the valve plate completely closes the cover opening, and a fully open position, in which the valve plate fully opens the cover opening. The valve core and motorized rotation provide complete sealing of the pressure relief valve, enhancing waterproof, dustproof, and smoke-proof performance.
